Novel organic-inorganic interpenetrating polymer networks(IPN) involving sodium alginate and silicon dioxide were synthesized through hydrolysis and condensation of tetraethoxysilane(TEOS) in sodium alginate(SA).The intermolecular interactions and miscibility of the prepared IPN membranes were characterized by Fourier transform infrared spectroscopy(FT-IR),transmission electron microscopy(TEM) and scanning electron microscopy(SEM).The effect of SiO2 on the crystal property of SA was demonstrated by X-ray diffraction(XRD).FT-IR shows that chemical bonds as well as hydrogen bonds are generated between sodium alginate and SiO2.TEM and SEM demonstrate that good compatibility is achieved in molecular level through the impenetrating of SiO2 network in SA.
